I find it hard to believe that Grado would change the engraving because Les complained, or because of the complaining on HF started by Les' "blurry" post. But even if Grado did decide to change it for that reason, the fault still lies with them for making the decision to change it, and then not ensuring that it was done correctly. Les' complaining about the original may be annoying, but he deserves no blame for the engraving problem.
